SumOffice for .NET

Create documents without Office. To show them to people and let them edit in a browser — use SumOffice Server.

The package works without a screen for XLSX/XLSM, DOCX and PPTX. It contains no viewer or browser editor. Office.CoreVersion() returns the packaged core release (2026.4.5). The current server opens /d/<document-id> from a configured host or folder and has no local-file upload API.
